PostFX screen space warp materials;

Version 1.3 and 2.0 for Blender 4.3 (EEVEE next);

Version 1.3 (25/11/24):

    - Water refraction fix;

Version 2.0 Experimental (27/11/24):

    This is not a replacement for the first version, just a rework for Blend Mode materials. It's an experimental branch, and it's a bit problematic, but overall works ok, it doesn't require raytracing in order to work and be able to project transparent objects with dithered material in the background.

Version 1.2.2 (23/11/24):

Version 1.1.1 (22/11/24):

    This method has it's pros and cons, most importantly, its limited to the viewport/camera view, and a lack of screen data causes black stripes at edges (in a few instances this can be negated by setting "Effect Strength" to a negative values in the shader editor); This is similar to game engines implementation, except it doesn't wrap image on sides;

    It's achieved by warping the coordinates of the final render image with shader-generated vectors and applying them in the Blender compositor; The result isn't accurate, refraction is limited to screen space and mostly useful for stylized, not realistic results. You can disable/enable needed effects as they are grouped and named for easy tuning; I made this project originally to warp "air space" around objects, but got carried away and tried to make stylized water refractions (so it's a bit simple);

    Effects are tied to framerate (30 fps as default), you have to manually adjust values in the shader editor to suit your needs;
